Calculation of the sum of a column on a XML editor RTF with NULL values

Hello

I have a problem to get the sum of a column in XML editor RTF, if one of the lines has a null value.

say, I have 4 columns and values

CASES1:
NULL, NULL, 4, NULL
Sum, I expect is: 4

CASE2:
NULL, NULL, NULL, NULL
I'm waiting for is a null

Is there a way to do this?

Thank you

Is there an alternative way to compute the sum of a column without accessor view

Hi Experts,
JDev 12 c,
I have a column A and I'm total calculation of column A with the same VO as a view accessor. And calculating as below
EmployeeViewAccessor.sum ("ColumnA").
But this way, it loads the VO 2 times as it loads the accessor aswell.
So is there an alternative way to calculate the sum of a column.
Thank you
Roy

How to display the line empty as a line with null values
Hi all

Pls advise me if it is possible to use a single query statement to display
Empty row (i.e. not a single return line) as a line with null values.

For example,.

JavaScript for the sum of a column cells

Hi all -
I have a table in expansion (lines can be added) and I am using the line of the column footer to calculate the average of the cells which do not have the value 0.
Form Calc is usually great, but in this case, I need to divide the sum by the number of cells that are not zero and I don't know how to do this via form Calc.
Successfully used javascript to identify the total number of occurrences and identify the number of instances that are zero, then the part of the denominator of the equation is fine. (Number of cases - number of zeros = denominator.)
Now, it's just the numerator. There must be a loop, right?
Is called table: table1
Line is called: data
cell is called: rated
Any thoughts? Or more effective methods? Thank you very much.

Hello

a solution in FormCalc could look this way:
```
form1.#subform[0].table1.footer.sum::calculate - (FormCalc, client)
var c = 0
var s = 0
for i = 0 upto (_data.count - 1) do
  if (data[i].eValue gt 0) then
  c = Sum(c, 1)
  s = Sum(s, data[i].eValue)
  endif
endfor

if (s gt 0 and c gt 0) then
  $ = Round(s / c)
else
  $ = 0
endif
```
Put this scriot in the calculate of the cell of the footer line event.

How to get the last row and the sum of all columns in a query

Hello
is there a way to get the last record for a column and the sum of all the Archives to another column in the same query.
Best regards

You must set your needs correctly volunteers to help here...

Your data are not good enough to bring you a precise solution. Purpose, you do not have a column, which draws a distinction between the first and the last entry.

The solution becomes easy based on your design.

I introduced a grouping called 'id' column and a time column called 'time_of_insert' (only this way you can say with confidence that you can differentiate between the first and last (also a foolproof solution) - you can possibly use sequence (instead of date but if you say that you can insert two lines at the same time) ((and then likely sequence would be a better choice to differentiate instead of a timestamp field) etc...)

With your sample data, something like this can be done to get the desired results.

-----------------------------------------------------------------------------------------------------------------------

WITH dataset AS

(SELECT 1 id, 10 used, 8 remain, systimestamp + 1/24 time_of_insert FROM DUAL

UNION ALL

SELECT the 1 id, 1, 7, systimestamp + 2/24 FROM DUAL

UNION ALL

SELECT the id 1, 2, 5, systimestamp + 3/24 FROM DUAL

UNION ALL

SELECT 1 id, 1, 0, systimestamp + 4/24 FROM DUAL

UNION ALL

SELECT 1 id, 0, 0, systimestamp + 5/24 FROM DUAL

UNION ALL

SELECT the 1 id, 1, 4, systimestamp + 6/24 FROM DUAL)

SELECT *.

(SELECT SUM (used) ON sum_all)

FIRST_VALUE (stay)

COURSES (PARTITION BY id ORDER BY time_of_insert DESC)

last_row

Of THE dataset)

WHERE ROWNUM = 1;

Output:

------------------------

SUM_ALL LAST_ROW

15 4

A simple query to write for the SUM of a column

Hello

I have a Quantity column. I want his total.
For a PURCHASE, I would like to add the value in the column Qunatity.
For a COPY, I want to subtract the value in the column Qunatity.
So overall, the sum of the column should give me total buy less total sells.

Any help is welcome.

Alter the State of Session? -Apex form publishes text with null value
Recently I discovered a problem with our Apex facility in which all selected as source for a text field value will eventually be displayed as a null value in the database.
We run APEX version 3.2 in an Oracle 10.2.0.4 database using Oracle HTTP Server from 10 g companion disc.

At first glance, everything seems to work as expected; I created a simple table called "oracle_sr" with 2 columns, as both not null:

SQL > desc capacity.oracle_sr
Name Null? Type
ORACLE_SR_ID NOT NULL NUMBER
TIMESTAMP NOT NULL DATE

In APEX, the form wizard has been used to create a form on this table.
After execution of the pages and you enter a value for the timestamp field, I can create folders without problem.

The question arises when I choose a source for the timestamp field value.
All the source options causes the same error (including a static value) so I'll focus on the SQL query to the source as:

Select sysdate double;

This should replace the date system in the area of text timestamp when the page is executed.
As expected, the value appears in the text box, but when I submit the form to create the folder I get the error:

ORA-01400: cannot insert NULL into ('ABILITY'. "" "" ORACLE_SR '. "" TIMESTAMP")

I have worked with APEX for quite awhile and have successfully used this technique in many applications but just to begin to see this error in recent days. What's particularly odd about this message is by default postings "not null" created by the form wizard sees timestamp class as having a value. Session state information included below reports a value yet the database is to launch the ORA-01400.

Someone has a similar problem? I have spent a good amount of time to try looking for this problem but can't seem to find any similar messages.

I have included the release of my test page, debugging from what I see, it seems to be a value associated with the filed timestamp:

If you have changed the Source Type of an element of database column to something else, so he cannot participate in the automated line choreography Fetch/automatic line processing (DML). You must leave the Type of Source, as it was and change the default value of the element fill when the ARF process retrieves a null value for the column.

Add filter slot table form to show the lines with null values
Hello

I have a tabular presentation where we need to add a filter with two values (selection list) so that if one of the columns in a table (column1) is zero, then I need to display all records where column1 is null.

I was wondering how do I put this in the Source of tabular forms where condition. This filter has only two values,

All the
NULL for the error

So when the user selects all, then all the records in the table are shown
If the user selects 'Value Null in error', while the records where Column1 is null will be shown

For example
```
 column1        column2
                       A
                       B
      1               C
      3               D
 
```
If the user selects, then

all four files will show up. Else, only the first and the second will be returned.

Thank you
Hi, Ryan.

Try a static LOV like this
```
STATIC2:;,--- All ---;--- All ---
```

REGEXP_SUBSTR for the list delimited by commas with null values

Hello

I have a column that stores a list of values comma-delimited. Some of these values in the list may be null. I'm having some trouble trying to extract the values using the REGEXP_SUBSTR function when null values are present. Here are two things I've tried:

SELECT
   REGEXP_SUBSTR (val, '[^,]*', 1, 1) pos1
  ,REGEXP_SUBSTR (val, '[^,]*', 1, 2) pos2
  ,REGEXP_SUBSTR (val, '[^,]*', 1, 3) pos3
  ,REGEXP_SUBSTR (val, '[^,]*', 1, 4) pos4
  ,REGEXP_SUBSTR (val, '[^,]*', 1, 5) pos5
FROM (SELECT 'AAA,BBB,,DDD,,FFF' val FROM dual);

POS P POS P P
--- - --- - -
AAA   BBB

SELECT
   REGEXP_SUBSTR (val, '[^,]+', 1, 1) pos1
  ,REGEXP_SUBSTR (val, '[^,]+', 1, 2) pos2
  ,REGEXP_SUBSTR (val, '[^,]+', 1, 3) pos3
  ,REGEXP_SUBSTR (val, '[^,]+', 1, 4) pos4
  ,REGEXP_SUBSTR (val, '[^,]+', 1, 5) pos5
FROM (SELECT 'AAA,BBB,,DDD,,FFF' val FROM dual);

POS POS POS POS P
--- --- --- --- -
AAA BBB DDD FFF

As you can see that neither calls work correctly. Anyone know how to change the regular expression pattern to handle null values? I tried various other models but could not get anyone to work in all cases.

Thank you

Hi, Martin,.

That's what you want:

SELECT
   RTRIM (REGEXP_SUBSTR (val, '[^,]*,', 1, 1), ',') pos1
  ,RTRIM (REGEXP_SUBSTR (val, '[^,]*,', 1, 2), ',') pos2
  ,RTRIM (REGEXP_SUBSTR (val, '[^,]*,', 1, 3), ',') pos3
  ,RTRIM (REGEXP_SUBSTR (val, '[^,]*,', 1, 4), ',') pos4
  ,RTRIM (REGEXP_SUBSTR (val || ','
                      , '[^,]*,', 1, 5), ',') pos5
FROM (SELECT 'AAA,BBB,,DDD,,FFF' val FROM dual);

The query above works in Oracle 10 or 11, but in Oracle 11, you can also do it with only REGEXP_SUBSTR, without using RTRIM:

SELECT
   REGEXP_SUBSTR (val, '([^,]*),|$', 1, 1, NULL, 1) pos1
  ,REGEXP_SUBSTR (val, '([^,]*),|$', 1, 2, NULL, 1) pos2
  ,REGEXP_SUBSTR (val, '([^,]*),|$', 1, 3, NULL, 1) pos3
  ,REGEXP_SUBSTR (val, '([^,]*),|$', 1, 4, NULL, 1) pos4
  ,REGEXP_SUBSTR (val, '([^,]*),|$', 1, 5, NULL, 1) pos5
FROM (SELECT 'AAA,BBB,,DDD,,FFF' val FROM dual);

The problem with your first request was that he was looking for sub channels of 0 or more non-virgules. There was as a substring. consisting of 3 characters starting at position 1, he returned "AAA", as expected. Then there was an another substring, the 0 characters, starting at position 4, so it returned NULL. Then, there was a substring of 3 characters starting at position 5, so he returned 'BBB '.

The problem with your 2nd request was that he was looking for 1 or more non-virgules. 'DDD' is the 3rd this substring.

ORDER BY a column with NULL values only
Hello

The order of column has all null values for the results of my query set.

Ex:

Select a, b, c from table1 where type = 'type1' and ID = "id1" order by column1

In the above query, "column1" contains nulls for 'type1 '. The order of the records in the result set is different for different ID values if the values of a, b and c are always the same.
What is happening in the 10g database.

I have also observed that the order of the records for the same query conforms in the 9i database.

(1) is the difference due to the difference in versions of database?
(2) is there a way to get the order even records independently entry ID?
(3) I cannot in the same order in 10 g DB too as the order in 9i DB?

Thank you.

If two or more rows have the same values (or NULL) for each ORDER BY expressions, then you may not be sure what order they will be. The system is free to do whatever he finds convenient. What the system identifies Dresser can vary depending on many factors, including the version, the size of the table, the conditions in the WHERE clause, there is a GROUP BY clause, or not... In all cases, it is not something that you can depend on. If you want the output in a certain order, to specify the order in the ORDER BY clause.

(1) is the difference due to the difference in versions of database?

Could be. In all versions, Oracle said that you cannot count on the order being compatible, except if the ORDER BY clause, it is consistent.

(2) is there a way to get the order even records independently entry ID?

Add more expressions at the end of the ORDER BY clause, as tie-breakers.
For example:
```
ORDER BY  column1
,         a
,         b
,         c
```
If table1 is really a table (not a view), you can add a ROWID.
In most cases, you can ORDER BY expressions that are not in the SELECT clause. So if you have a primary key, you can usually ORDER BY it, even if you don't see it.

(3) I cannot in the same order in 10 g DB too as the order in 9i DB?

Of course, ORDER BY works the same in all versions. If you have an ORDER BY clause to unambiguously, the output will be exactly the same order in any version.
Remember that the absence of ORDER BY has no effect in all versions. If you have an ORDER BY of ambiguous clause, you can not count on the coming out in a particular order in any version.

NPE for rows with null values in the table of the adv
I created the table adv, 2 columns, equipped with two text fields. Initially the col2 is empty,
say that the structure is as follows:
```
              col1          col2
Hdr         Question    Answer
row1       abc           zxc
row2       pdd           null (user doesnt enter anything)
row3       zxc            lkj

APPLYBUTTON
```
When the user clicks on apply button I want to update these values in the table.

I don't know how to do that, but that's what I'm trying to do. Please guide me the right way if its wrong.

in LICS, I took the APPLYBUTTON action, got all lines of the object corresponding to the view, consulted with everyrow and I'm checking if there are values in the fields in the table, if the value zero, are simply print null. (we would not update on this line). . I could get o the part update, due to null pointer exception
I get on the row line null pointer exception [1].getAttribute("Answer") for row2, it prints the value of row1 however.

Here is the code I wrote:
Set of rows from the rowset = (RowSet) vo.getRowSet ();
Rank rank [] = vo.getAllRowsInRange ();
System.out.println ("row.length" + row.length);
for (int i = 0; i < row.length; i ++) {}
String question = row.getAttribute("Question").toString ();
String response = row [i].getAttribute("Answer").toString ();
If (question! = null & &!("".)) Equals (question. Trim()))
{
System.out.println ("Question line" + i + "-" + question);
}
on the other
{
System.out.println ("Question line" + i + "is null");
}

If (response! = null & &!("".)) Equals (Answer.Trim ()))
{
System.out.println ("Response line" + i + "-" + response);
}
on the other
{
System.out.println ("Response line" + i + "is null");
}

Why the NPE survey code, I'm checking for null value and you want to print the value null in the logfile... I can not to getAttribute() on the null field, why can not just give me null in the variable I'm assigning to?

You can guide me what approach to take, if it is not correct.
I must examine DataDictionary and collect data there?
Thanks in advance.
Hello

handle the exception of null on these two statements like this pointer

String question = "";
String response = "";

Try
{
question = row.getAttribute("Question").toString ();
}
catch (NullPointerException e)
{
question = "";
}

Try
{
answer = row.getAttribute("Answer").toString ();
}
catch (NullPointerException e)
{
response = "";
}

Si ( !("". Equals (question. Trim()))
{
System.out.println ("Question line" + i + "-" + question);
}
on the other
{
System.out.println ("Question line" + i + "is null");
}

Si ( !("". Equals (Answer.Trim ()))
{
System.out.println ("Response line" + i + "-" + response);
}
on the other
{
System.out.println ("Response line" + i + "is null");
}

Thank you

display of the output cursor empty with null values

I have the below procedure of the State where he is shown the output to the client.

The requirement now is if the select statement does not return a value any with the input given then output parameter should see NULL values instead of no line at all.

One method is to get the number of the select query that is written in "open p_out for." And then write the condition as if count is 0 then null other show data.

Could you please suggest me any other alternative to this.

Create or replace procedure test (p_empno in number , p_out out sys_refcursor) is

begin
 open p_out for 
 select e.ename, d.deptname, s.sal , p.addr , v.age
  from emp e ,dept d, sal s, padress p , age v
 where e.deptno = d.deptno and d.deptno = s.deptno
 s.sal_id = p.sal_id and p.id = v.id
and e.empno = p_empno ;

 
exception when others then
 open p_out for 
 select null , null,null,null,null from dual;

 
end test.

Thank you
